To all whom it may concern.

' Be it known that Gnome W. GWINN and Jams W. 'Lmnr, citizens of the United States, residing, respectively, at Brooklyn,

a county of Kings, State of New York, and Hollis, county of Queens, State of New York, have invented certain new and useful Im rovements in Stamp or Label Applying achines, of which the following is 9 a s ecification.

his invention pertains to an improved stamp or label app ying machine.

The invention has for its primary object the provisionrof a nove means for transferring the pasted stem or label from a table upon which it is aid out 1n its pasted condition into positlon 1n the path of an advancing package which withdraws the stamp from its temporary support and causes the stamp to adhere thereto. 7

A further object of the invention is to provide a special form of runway which holds the stamp ends in close contact w th the package so as to ensure proper adhesion 2 between the ackage 'and stamp and the drying of the a esive.

A still further object is to provide a special form of carrier for the packages which carrier serves to clamp the central. .portion of the stamp and to hold it in intimate contact with the package end until the stamp becomes suficiently dry, at which time the package is released and discharged.

With these and other objects in view,

reference will be had to the annexed drawings, wherein: 0

The term stamp is herein employed as the equivalent of a label, closure strip or the like, and the claims are to be read with this 1n v1ew.

Referring first to the construction illustrated in Figs. 1 to 12, inclusive, 1 denotesthe bed of the machine above which and extending lengthwise thereof are two bars or plates (see Figs. 6 and 7 2 and 3, supported by suitable brackets 4, said bars forming the side elements of a runway for the packages while a second pair of bars 5 and 6 placed between and at a lower,level than bars 2 and 3, form the bottom of the runway. Said bars 5 and 6 are sustained by suitable brackets 7. A fifth bar 8 is placed between the bars 5 and 6, said bar lying in a lower level and bein held in. place by bolts 9 and suitable spacing blocks 10. The side bars 2 and 3 terminate well short of the outer edge of the bed of the machine, see Fig. 5, while the bars 5 and 6 extend the full length of the runway. The lowermost and centrally disposed bar 8 forms the support and guide for the upper run of a package advancing chain 11, said chain being provided with a series of spaced lugs 12 carrying at their outer ends push plates 13 adapted to contact the rear pincer ends of the ackages, denoted by 14:, and to advance the same through the machine. @hain ll-passes about sprockets 15 and 16 located at the intake and discharge ends of the runway and beneath a driving sprocket l? secured to a driven shaft 18.

Sprocket 15, see Figs. 1 and 5, is supported upon a shaft 19 carried by a bracket 20 secured to the bed 1, while sprocket 16 is unted upon a shaft 21 carried by the outer ends of bars 5 and 6 or brackets secured thereto. The chain is given a continuous motion and the packages are placed thereon or fed thereto one at a time in front of the advancing push plates. The bars 5 and 6 form the bottom of the runway throughout the length of the machine and the bars 2 and 3 the sides thereof up to the point of placement of the stamp indicated by 22, see Fig. 6, where said bars stop. The sides of the runway are next formed by a pair of oppositely disposed brushes 23 24, each brush besupported by a short rod 25 adjustably secured in the upper end of a bracket 26 Secured to the bed 1. As the package leaves the brushes with the ends of the stamp wiped down against the sides of the packa it passes between two oppositely disposed plates 27 and 28, the ends of which, adjawnt the brushes, are flared outwardly so as to ensure the entry of the package therebetween. Said plates are attached to a pair of opwsitely disposed heaters 29 and 30, each heater being provided with a pair of outwardly extending cars 31 and 32, which ears, respectively, are pivotally at tached to the upper ends of levers 33 and 34, and to which they may be secured in their adjusted position by screws 35 passing through slotted extensions 36 formed upon the levers. The levers 33, see Fig. 5, are secured at their lower ends to a shaft 36 journaled in brackets 37 secured to bar 6, while the levers 34: on the other side are secured to stub shafts 36 journaled in brackets 38 secured t rail or bar 5.

To hold the inner adjacent faces of the heaters in their proper relation so that they will press the stamp ends against the packages as they are passed between them, the heaters are provided, respectively, with upstanding lugs 39 and 40, and a spring 41 attached to pins 42 and d3 extending from the lugs serves to draw the heaters toward each other. A handled lever 44: is pivoted. to lug 39 and a link 45 is likewise pivoted to lug 40 and to lever 14:; by this arrangement the heaters may be readily separated when for any reason it mes necessary or desirable so to do. The heaters may be heated in any desired manner, as, for instance, by gas or electricity, and form the outer portion of the runway serving to iron the ends of the stamps down and to dry the neeaeaa e. The fact that the are adjustable toward and from each ot er and are held against the packages by spring ressure, enables them to be adjusted t pee ages of difiercnt sizes -11 ZlJi ensures the proper pressure being exerted a ainst the stamp ends.

The stamps are esigned to be pasted from end to end and to be placed one by one across the path of the advancing packages. To that end there is employed a pasting mechanism, a table upon which the stamp is laid with the adhesive side down, a stamp transferring mechanism which takes the pasted stamp from the table and carries it into the path of travel of the packages, and a stamp holding or positioning means which receives the pasted stamp from the transferring mechanism. The table is denoted by 46 and is supported adjacent its ends by brackets 47 and 428, see Fig. 7. it is preferabl produced from a thin plate of metal and the upper surface is oothed ad or planished. It is likewise provided with two spaced notches i9 and 50 at its forward mge, the pose of which will presentl appear.

T e mechanism for feeding the stamps one by ne, applying paste thereto and laying them out in adhesive contact with the table may be of any approved form, that shown being the same as that set forth and claimed in the application of Geore W. Gwinn, Serial No. 839,835. lit may bdescribed in a general way as follows: The

stamps are stacked in a reservoir or holder 51 with the lowermost stamp resting at its ends upon inward projections 52, 53,. see Fig. 7. Said holder is mounted for vertical reciprocation upon a vertically disposed slideway 54, secured to the outwardly extending arms of columns 55 rising from the table 1, said reciprocation being effected by a cam 56, a link 57, a lever 58 connected to the latter, and an arm or pin 59,

which engages the holder or a portion therei i of. Such vertical reciprocation is for the purpose of carrying the lowermost stamp in contact with a pair of constantly rotating stamp withdrawing rollers 60 and 61, which pull the stamp out and feed the a wardly in a doubled condition. As the downdamp is withdrawn the stamp holder is elcvated t carry the same out of range of the rollers; Said rollers are driven through suitable gearing as shown in Fig. 10, wherein gear 62 is secured to one of the roller shafts and carries a pinion 63 which meshes with a pinion 64 upon I the other shalt. Gear 62 derives its motion from gear 65 mounted on a shaft with worm gear 66 i which is driven by a worm 67 secured to a cross shaft 68, the latter deriving its motion through chain 69 driven by sprocket 76 secured to shaft 18.

The stamp withdrawing mechanism is about each of said about similar meaeaa mounted on a cross piece or bracket member 71 secured to columns 55, and said member forms the su port for twohangers for two shafts 72 an 73 provided at the rear with intermeshing gears 74 and 75,-the latter deriving motion from car 65 with which it meshes. Each of said shafts at its forward end carries a grooved pulley 76' and ullefys passes a pair of belts 77, 78, the be ts 0 each pair passing ulleys 79 secured to shafts 80. Each sha t 80 carries a bevel gear 81, see Fi 5, which meshes with a gear 82 secur to cross shaft 68.. The belts at the outer end of their run pass over paste restripes and to spread or extend it out, pasted side down, on the table 46. To roperly 'dethe stamp as it passes doub ed upon itself from the feed rolls, there is provided a stripper and guide comprising two fingers 87 and 88 which pass down between the pulleys 76, see Fig. 7, the fingers being formed as extensions of a cross piece 89. Said piece is secured to a carrier 90 provided with an upwardly projecting arm 91, see Fig.12. The carrier is pivotally mounted on a lever 92, which at its opposite end is fulcrumed on a stud 93 secured in standard 94. A rocking motion is imparted to said lever through ink or rod 95 connected to a second lever 96 fulcrumed on a fixed shaft 97, a roller on the lever 96 taking into a cam 98. A radius bar connected to arm 91 at one end and at its opposite end to an adjustable arm 99 causes the fingers 87 and 88 to move in the'vertical and to properly the. table 46, and from that moment it is.

unfolded and carried laterally in both directions by the belts, see Fig. 7, until it is finally laid fiat upon the table. It is then necessary to remove the stamp from the table and transfer it into the path of the oncoming package with the pasted side toward the package. To do this a pincer mechanism is employed which grasps the stamp and giving it a bodily quarter turn deposits it in a holder in line with the oncoming package. The stamp is grasped at two points or where its edge is exposed through the table openings 49 and 50. The pincer mechanism is a dual one, hence similar parts are numbered alike.

Mounted in suitable bearings formed in the brackets or standards am 4s: is a mesh with gears 100. 'Gear 106 (in each instance) is secured to. a shaft 107 mounted in a bearing 108 formed with the standard 47 (or 48) and secured tothe inner end of the shaft is a double armed lever109. Said lever is in vertical alinement with the overlying slot or notch 49 v(or 50) and each of its ends forms one element or jaw of a p1ncer,'there being two such pincer mechanisms on each lever. Each arm of the lever is of such length that when it is turned to the vertical it will pas into the notch in the stamp receiving table and contact (or nearly so) the under face of the stamp, WhlCh 1s exposed at that point. Each arm of the lever is likewise formed with a hub 110 throu h which passes a bolt 111 and upon whic is fulcrumed the movable pincer jaw. Said member is of the form best shown in F1 8 and comprises a hooked shaped latera y deflected jaw element 112, a central body portion 113 having an o ning 1 14 therein for the passage of be t 111 and a laterally projecting boss or' lug 115. A pin 116 carryin in o ening 114 an a in 118 extends outwar ly in the same irection from body 113. A spring 119 having one end secured in the head or bolt 111 encircles the bolt, the opposite end being secured to pin 118.-

Said spring acts to swing the movable jaw and to bring it into clamping relation to the fixed jaw. A cam 120, see Figs. 3 and 4, secured to bracket or standard 47 (and 48) stands in the path of movement of roller 117 and serves to release the, movable jaw from its clamping relation with the stamp, Fig. 4, when the stamp is brought or carried into the path of the oncoming package. While the lever 109 moves continuously the swinging jaw when the roller contacts the cam will. be given a quicker movement hence the stamp is readily released. As the roller 117 passes from cam 120, pin 118 comes into contact with a second cam 121, thus holding the jaws apart until the end of the lever 109 directly underlies the stamp, at which time, see Fig. 3, the pin 118 passes from the cam 121 thereby allowing the pivoted jaw to swing rearwardly above the stamp and. to grasp the same. Inasmuch as the rotation of the levers 109 is continuous the stamp is withdrawn or stripped from table 46 and carried down! wardly into the path of the oncoming package. As it reaches this point it passes into a roller 117 is secured a holder comprising two vertically disposed forked orslotted arms 122, see Figs. 3 to till AIL

6, which are secured in position by brackets 123 attached to the rails 5 and 6. When the pinoers have moved throu h an arc of 9Q cams 120 again contact ro ers 117 and s1- multaneously open the jaws 112 thereby rcleasing the stamp which at that moment stands edgewise in the forked member 122, the stamp adjacent its ends coming to rest upon arms 124: which take the form best shown in Fig. 6, and secured to the brushes 23 and 24 respectively. While the outer supports are not absolutely essential, particularly it the stamp be a short one, they act to roperly support the ends of a long stamp and keep the ends from curling over. It will thus be seen that the stamp is positioned across the package runway with the pasted side standing directly in the path of the advancing packa e. It will likewise be seen that immediately one stamp is removed from the table another is being pasted and spread thereon ready for the gripping action of the second pair of pincers. As the package is advanced it contacts the stamp which is drawn endwise through and from the supports 122, the ends being laid rearwardly along the sides of the package by reason of the fact that the supports aline with the side rails 2 and 3. The package immediately passes between the brushes, thence between the plates 27 and 28, and finally between the heaters or ironers 29 and 30, being discharged therefrom onto a table or conveyor (not shown).

' There is thus provided a simple and effective machin which may be operated at a high speed with a minimum expenditure of power.

Under the construction above set forth the packages travel on their sides and the stamps extend entirely across the top and down the narrow edges. In F ig. 13 there is shown a modified form of package advancing means adapted to carry the packages on edge so that the stamp is applied across the top and down each side. The stamp pasting and positioning mechanism is the same as above set forth, but the package advancing means is modified. It may be said to comprise a series of interconnected carriers forming in effect a chain. Each carrier comprises a table or platform like member 124: having two downwardly extending legs 125, 126, each leg having a roller 127 upon its lower end which ride upon a trac or rail 128. At its rear end the table or carrier is provided with an upstanding arm 129 against which one end of the package abuts. Pivotally connected to the lower end of leg 126 is an elbow lever, the lower arm 130 of which carries a roller 131 adapted to contact cams 132 and 133 successively. The upwardly extending arm 134 of the lever is of a width somewhat less than the thickness of the package and menses is drawn into contact therewith under the action of a spring 135 attached to said arm and the under portion of the table or platform 124. Cam 132 serves to swing the arm to open position so that a package may be positioned and cam 133 again opens it so as to admit of the positioning of a stamp in the stamp support 122 and between the package and the then opened or retracted clamping arm. The legs 125 and 126 of adjacent carriers ar connected b a pair of links 136, 137, and the chain li e structure thus produced travels about pocketed sprockets 138 and 139, the latter being driven through sprocket chain 140 from the power or driven shaft 18. Suitable means for wiping down the ends of the stamp and can ing it to adhere to the sides of the paclc age, as in the construction above described, will be employed. The clamping arm or element 134 presses the central portion of stamp directly against the package end. is conceivable, of course, that but single pair of pincers may be employed and the package advancing mechanism timed accordingly. The dual arrangement is preferable on account of the higher speed which the machine may be operated.
